METAL WHEEL.

Application led January 17, 1921, Serial No. 437,642. Renewed February 17, 1923.

To all whom it, may concern:

Be it known that we, CHARLES SCIENCE vand CYRUs W. BAssE'rr, citizens of the United States, and EMIL IBACH, a citizen .5 of the Republic of Germany, residing at Bethlehem, Northampton County, Pennsylvania, have jointly invented new and useful Improvements in Metal Wheels, .of which the following is a specification, reference being had to the accompanying drawings, in

which- Fig. l is an elevation of a wheel embodying our invention; Fi .2 is a section on lines II--II of Fig. 1; an Fig. 3 is al section of 16 a modified form of our invention.

Our invention relates to metal wheels and comprises a wheel in which the rim, web,

spokes and an annulus in the region of the hub are all cast in one piece. Our invention also consists in the features which we shall hereinafter describe and claim.

Referrin to the drawings, 2 indicates the rim of t e wheel, which in section is preferably of a gradually increasing thickness fromthe edges toward the center, where it joins a continuous web 3 arranged at right angles thereto. The spokes 4 l`are joined to the web 3 in the plane of the web, but as they extend toward the hub they are splayed or staggered alternately so as to form two sets of spokes, one on either side the plane of the web. At their inner ends the spokes 4 merge into an annulus 5, which has a box like section, the inner face 6 of which forms a bearing against the exterior of the hub 7.

The vertical faces of the annulus 5 are engaged by a flange 8 'on the hub and by a plate 9, which is apertured to slip over the hub barrel. The flange, plate and annulus are secured firmly together by the bolts 10.

The spokes 4 are preferably formed with ribs 11 thereon, which serve to give additional strength thereto.

vv We prefer to form the wheel, just de- 'but extending in the direction of the hub scribed, by-casting, so that it may, with the exception of the hub, be made in one piece. We have found that a wheel formedin the manner described is much lighter than the usual type of cast wheel, owing to the skeletonized form of the wheel and to the comparatively thin sections of the spokes and the hollow section ofthe annulus. In Fig. 2 we have indicated core openings 12 through which core sand may be removed 'from the annulus 5. Theseopeningmay, if desired, be closed in` any suitable manner after the removal of the sand. I

In Fig. 3 we have shown a modified form of our invention, in which the hub 7a is cast integral with the annulus of the wheel.

The terms and expressions which we have employed are used as terms of description and not of limitation, and we have no intention, in the use of such terms and expressions, of excluding any mechanical equivalents of the features shown and described, or portions thereof, but recognize that various structural modifications are ossible within the scope of the invention c aimed.

What we claim is:

1. In a metal wheel, a continuous rim, a web emerging from the inner `face of the rim and at right angles thereto, spokes attached to the web in the plane of the web,

out ofthe plane of the web, and an annulus in the region of the hub into the sides .of which the spokes merge, the parts being cast integral.

2. A metal wheel, having a continuous rim, a web attache-d thereto, a bearing for the hub, sets of spokes, each' set extending from the web to a face of the hub bearing, the said parts being cast integral.
